I think however that they <em>can</em> use beta -- which is branchign very soon -- so long as they don't use any feature-gates. So maybe it's not blocking them <em>that</em> badly, though they'd prefer to use stable. Also, ThinLTO is an advertised feature that others might want, and you need this fix to use it.</p>
